Pond UV Clarifiers & Sterilisers

Green algae is not necessarily a sign of poor water but quite the contrary Koi and wildlife have no problem thriving in water with green algae present.

Ultra Violet Clarifiers and Sterilisers are primarily used on a pond or water feature to keep the water crystal clear and reduce green algae growth to enhance your enjoyment and ability to see through the water and the fish in the water.

Ultraviolet wavelength

There are two main types of UV units available. UV Clarifiers and UV Sterilisers.

UC clarifiers are used to kill green algae where as UV sterilisers, sterilise the water passing through the emitted rays killing 99% of algae and bacteria making them a much more effective piece of equipment.

However both UV clarifiers and sterilisers will keep your pond water free of green algae so long as they are sized and installed correctly.

As a general rule of thumb 10 watts per 1000 UK gallons of water is a minimum but can be increased if pathogen reduction is desired.

For help selecting the correct UV for your requirements please don’t hesitate to contact the team at Utopia Koi and we will be happy to help.

Please ensure that all delivered UV clarifiers and replacement bulbs are thoroughly checked upon receipts and signed for un-checked or damaged to ensure a delivery damage claim can be made.
